Description
Stopcock plug with thread, ground, made of SBW-J glass, NS 12,5 and 2 mm bore is a solid stopcock key intended for secure mounting in laboratory glassware. The massive SBW-J glass plug carries a thread onto which the three-part screw retainer is fitted, ensuring positive retention once installed. Ground surfaces and the defined taper of 1:10 provide a reliable seal within matching joints. These stopcock plugs are offered in three NS sizes, each available with two bore variants, allowing selection according to apparatus requirements. The component is produced from borosilicate glass 3.3 and is supplied by manufacturer Duran/DWK Life Sciences for use in glass apparatus construction. With its threaded design, solid body and precise NS 12,5 geometry, the plug supports assembly and maintenance of laboratory glass systems that rely on interchangeable ground stopcock elements. The 2 mm bore and screw-lock compatibility make it suitable for standard experimental setups requiring durable, replaceable stopcock fittings.

Questions about Stopcock Key, threaded, made from SBW-J glass, ground
What is this article?
Stopcock Key, threaded, made from SBW-J glass, ground is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
